I have a 1992 ford ranger 2wd 4.0L V6 with an AC system that is running off of R-12 refrigerant. From what I can tell there is no leaks, just bad compressor. But seeing how I can't get or use R-12 anymore, I need change the system out. Would parts from a 1994 ranger work in my 1992 If I was find it from a junk yard?
